Which statement about the use of tunneling to migrate to IPv6 is true?
A.
Tunneling is less secure than dual stack or translation.
B.
Tunneling is more difficult to configure than dual stack or translation.
C.
Tunneling does not enable users of the new protocol to communicate with users of the old
protocol without dual-stack hosts.
D.
Tunneling destinations are manually determined by the IPv4 address in the low-order 32 bits of
IPv4-compatible IPv6 addresses.
Tunneling has two disadvantages, as discussed in RFC 6144:
• Users of the new architecture cannot use the services of the underlying infrastructure.
• Tunneling does not enable users of the new protocol to communicate with users of the old protocol without dual-stack hosts, which negates interoperability.
